The ultimate lesson is one of humility -- i.e. "It's not about you." Arrogance and selfishness are limited, unfulfilling paths; learning to better yourself and following a path that isn't always easy provide greater rewards. Perseverance pays off. But rather than fight against a current, it can sometimes be better to surrender and use the current's power to your benefit. Argues that sometimes breaking the rules a little is necessary to get a job done. (And don't text and drive!)
Lots of mass destruction of buildings and property. A beheading (no gore shown). Frequent martial arts fighting, with some "magical" weapons (swords and whips made of light). Scenes on an operating table, with some bloody parts shown. Bloody scratches on the main character's face. Brutal car crash (character was texting while driving), with bloody hands and face. A terrible fall from a height, crashing through glass. Arguing. Some scary sequences (a brief nightmarish "journey" with grabbing hands).
Two characters have had an intimate relationship, and they talk comfortably together. Mention of "sleeping together."
One "s--t," plus a couple uses of "a--hole," "ass," and "hell."
A character buys Kettle chips from a vending machine; sign for Yakult drinkable yogurt. This is also part of the Marvel franchise, which has vast quantities of tie-in merchandise.
